2005-12-06[IA64] Change SET_PERSONALITY to comply with comment in binfmt_elf.c.Robin Holt
We have a customer application which trips a bug. The problem arises when a driver attempts to call do_munmap on an area which is mapped, but because current->thread.task_size has been set to 0xC0000000, the call to do_munmap fails thinking it is an unmap beyond the user's address space. The comment in fs/binfmt_elf.c in load_elf_library() before the call to SET_PERSONALITY() indicates that task_size must not be changed for the running application until flush_thread, but is for ia64 executing ia32 binaries. This patch moves the setting of task_size from SET_PERSONALITY() to flush_thread() as indicated. The customer application no longer is able to trip the bug.

2005-11-09[PATCH] remove ioctl32_handler_tChristoph Hellwig
Some architectures define and use this type in their compat_ioctl code, but all of them can easily use the identical ioctl_trans_handler_t type that is defined in common code.

2005-09-14[PATCH] error path in setup_arg_pages() misses vm_unacct_memory()Hugh Dickins
Pavel Emelianov and Kirill Korotaev observe that fs and arch users of security_vm_enough_memory tend to forget to vm_unacct_memory when a failure occurs further down (typically in setup_arg_pages variants). These are all users of insert_vm_struct, and that reservation will only be unaccounted on exit if the vma is marked VM_ACCOUNT: which in some cases it is (hidden inside VM_STACK_FLAGS) and in some cases it isn't. So x86_64 32-bit and ppc64 vDSO ELFs have been leaking memory into Committed_AS each time they're run. But don't add VM_ACCOUNT to them, it's inappropriate to reserve against the very unlikely case that gdb be used to COW a vDSO page - we ought to do something about that in do_wp_page, but there are yet other inconsistencies to be resolved. The safe and economical way to fix this is to let insert_vm_struct do the security_vm_enough_memory check when it finds VM_ACCOUNT is set. And the MIPS irix_brk has been calling security_vm_enough_memory before calling do_brk which repeats it, doubly accounting and so also leaking. Remove that, and all the fs and arch calls to security_vm_enough_memory: give it a less misleading name later on.

2005-09-12[PATCH] x86-64: Fix 32bit sendfileTsuneo.Yoshioka@f-secure.com
If we use 64bit kernel on ia64/x86_64/s390 architecture, and we run 32bit binary on 32bit compatibility mode, sendfile system call seems be not set offset argument. This is because sendfile's return value is not zero but the code regards the result by return value is zero or not. This problem will be affect to ia64/x86_64/s390 and not affect to other architecture does not affect other architecture (mips/parisc/ppc64/sparc64).

2005-09-07[PATCH] remove duplicated sys_open32() code from 64bit archsMiklos Szeredi

This gets rid of an unused variable `error' in sys_ia32.c:sys32_epoll_wait() Getting rid of this one makes parsing the output of the kernecomp autobuild easier --- searching for `Error' to find a problem kept hitting this one, even though it's only a warning.

2005-04-22[IA64] ia32_signal.c: erroneous use of memset/memcpyArun Sharma
Found by Alexander Nyberg, improved by Bjorn Helgaas. - Fix the incorrect argument to sizeof() - looks like memcpy() code pass was dervived from code that used copy_from_user(). But in this case we are doing to kernel space to kernel space copy, so memcpy is the right routine, but it doesn't return an error code.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
